Lightweight guides provide accuracy
boost
The Kwem-MKS linear guide has a metal end piece, which makes the unit suitable for high-temperature environments or for applications with high dynamic forces.
Schaeffler has expanded its range of miniature linear guidance systems, offering machine builders and designers lighter, more compact designs that provide optimum positional accuracy and repeatability, even in harsh environments The miniature plain guidance systems are linear locating bearings with at least one carriage

Chicken Run cameras turn on INA Bearings
Chicken Run, the highly successful film from Aardman Animation (famous for Wallace and Gromit), was made with the help of specially designed camera mounts incorporating INA bearings.
Ina website contains massive bearing databank
Access to data on most INA products is now freely available via a completely revised website at www.ina.com, which is in both English and German.
The units can support forces from all directions, apart from the direction of motion, and moments about all axes.
The guides are ready to fit and maintenance-free, for stroke lengths of up to 3m.
The carriage and guideway are both constructed from extruded, anodised aluminium and offer high resistance to chemical substances and other contaminants.

In anticipation of the demands from designers of future generations of machine tools, the INA Bearing Company has developed a range of innovative products.
New possibilities from crossed roller bearings
Two new series of crossed roller bearings from INA offer the potential for innovative bearing arrangements with a high performance/cost ratio.
The guides are suitable for use in lightweight, aluminium machine designs, as well as applications with low loads, moment loads, dry running or harsh environments.
Operating temperatures are from - 40 up to +80C.
Schaeffler's existing range of miniature profiled rail linear guidance systems is the Kwem double-row miniature ball monorail guidance system, which comes in four sizes with corresponding guideways (TKDM).
The units are extremely compact and are designed for medium load carrying capacity, medium to high moment loads, accelerations of up to 50m/s2 and speeds of up to 180m/s.
The double rows of balls are in four-point contact with the raceways.
The double row assemblies consist of at least one carriage with full-complement ball system, locating face and ball retainers, as well as a guideway with two locating faces.
The units are pre-loaded and greased and operate in temperatures from - 40 up to +100C.
Special seals are provided at the carriage faces to prevent ingress of dirt.
Re-lubrication is carried out via lubrication holes at the carriage end piece.
The guideways can also be combined with all available carriage types within the same size and preload class.
The Kwem-MKS has a metal end piece, which makes the unit suitable for high-temperature environments or for applications with high dynamic forces.
All metal parts are made from corrosion-resistant steel.
Miniature linear ball monorail guidance systems are suitable for applications in which linear movements of high positional and repeat accuracy are required.
They are suitable for use in production and technical mounting systems, assembly equipment, microelectronic systems, medical engineering and other high-precision handling machines. Request a free brochure from Schaeffler (UK) ...
